I had some professional mechanics look at it and there was nothing visibly wrong with the lockring threading or the lockring, but one guy told me that you can't always see what the problem is. I am thinking now that I should have tightened it as much as possible and then put on some loctite? Would it have been better to have put loctite on the exterior threading (i.e. the leftover thread after the lockring was on) or on the lockring or cog threads? Do people use loctite for this purpose?
Thanks for the replies RetroGrouch and JT
Small chance my problem was the same as yours, but... When I first set up my fixed gear, the lockring was getting loose. Turns out I put the Formula brand lockring on backwards. I think, due to its design, the lockring was not able to snug up against the cog tight enough before reaching the end of its threads, so it was susceptible to coming loose.
